AI-Powered supplier vetting

SummaryThe supplier manufactures and sells aluminum products, radiators, hardware, treated metal products, tents, and assembled lamps. It offers extensive customization, ODM, OEM, and SDK-related capabilities, with evidence of new product development during the past year. Quality and service processes are documented and followed, and the supplier states ISO9001:2015 and IATF16949 certification. Production-related evidence includes in-house tooling and parts production, available inventory, 65% stated capacity utilization, and valid contracts with associated subcontractors. The supplier has exported for 25 years, with exports representing 41%–50% of total sales, and supports several quotation terms. Financial credibility cannot be determined because the provided information only identifies reporting years and contains no substantive financial results. Customer-case evidence is limited to OEM service for unnamed well-known brands.

Supplier typeThe supplier is a manufacturer and seller of aluminum products, radiators, hardware, treated metal products, tents, and assembled lamps. Its description also states that tooling and parts are produced in-house, supporting classification as a manufacturing supplier rather than only a trading company.

CertificationsThe company description explicitly states that the supplier holds ISO9001:2015 and IATF16949 certification and complies with the RoHS Directive. These are direct indications of formal quality-management and product-compliance credentials.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, and service-capability assessment. It offers overseas-agent or branch support and in-stock service, but has no overseas warehouse or showroom; the evidence therefore supports established service processes but not comprehensive overseas infrastructure.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has an available SDK. These statements directly support active product-development capability, although no internationally recognized design awards are reported.

Production capacityThe supplier states that it performs tooling and parts production in-house, has sufficient capacity with only 65% occupied, maintains inventory capability, and has valid manufacturing contracts with associated subcontractors. Finished-product inspection instructions are available and uniformly followed, while peak- and off-season lead times are both stated as one month.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization. It also provides ODM services, indicating support for both customer-led and supplier-led product development.

Client casesThe supplier states that it provides OEM services for well-known brands, but no customer names, project details, product categories, or performance outcomes are provided. This supports the existence of some brand-serving experience but is insufficient to assess the quality or relevance of the cases in detail.

The minimum order is 300kg for a trial order, with one free sample available for approval.

Q:What are the lead times for samples and production?

Sample lead time is 15-18 working days (including 7-10 days for tooling if needed). Production lead time is 15-25 working days.

Q:Can the fin dimensions be customized?

Yes, the height, thickness of fins, and distance between fins are adjustable by changing the lathe tool without needing new tooling.

Q:What payment terms are accepted?

Tooling requires 100% prepaid by wire transfer. Parts require 30% upon order confirmation and balance before delivery via T/T. Other terms are negotiable.

Q:What materials are used for the heat sinks?

We use AL6061, 6063, 1050, and Pure Copper, ensuring 100% heat contact between fins and base.
